Delete items from a tree:
I'm trying to delete items from a tree. I used Ftree.Delete_Tree_Node (htree,: trigger_node);It deletes the node eventhough that the child exists. I don't want the user to remove an if child node exist.
How we do it.
How we count the childs in a selected parent node.
You can search for a child node of the node of your, if it exists, there are children, as
DECLARE
nd FTree.NODE;
BEGIN
nd:= FTREE.FIND_TREE_NODE('THETREE','',FTREE.FIND_NEXT_CHILD, FTREE.NODE_VALUE,:SYSTEM.TRIGGER_NODE,:SYSTEM.TRIGGER_NODE);
IF NOT FTree.ID_NULL(nd) THEN
-- there are children
END IF;
END;

Deleting items from the taskbar removes desktop as well
Elements of the desktop icon began appearing in the toolbar {(Articles 4 et 5).} If I click on one of these elements of the taskbar right-click and delete it, it is removed from the bar spots and the office. Another element of the office appears on the taskbar. The desktop and the taskbar are somehow. This just started today.
If you right click on the taskbar you can create a toolbar from the Office

How can I delete items from a 2D array?
Hi all!
I asked a similar question in the past, but I'm looking at a slightly different scenario now. I have a chart 2D of 8-bit values which form a video image, but I'm trying to remove a number of the highest values in the image. In order to avoid the image of being horribly ejected, I thought that I would like to replace these with NaN values. While I thought it would be simple, I had problems to access the items in the middle of a 2D array. I have attached my code, but I fear it will not be that useful, it was something of a poor attempt (but this is my most complete).
Thank you for your time ,.
-Gobble
First of all, eight bits (U8) have not NaN. Are you using the correct representation?
You can substitute a zero (for example) instead.
Here are two simple using tables DBL ways, because that's what you actually have. Modify if needed.

Hello
Need help with this one
Im a picture step by step construction (simulating the test data is stored in a table)
Lets say I took 4 samples and im on place 4 in the table.
Then I noticed that the last item I put in my table has an incorrect value and want to replace it with a new value in the same place.
My goal is then to check the values in the table and replace when I need to.
And it is important that the values before and after the removal of the elements is done only when you use the same table.
Were says:

I have no idea what you mean by that last sentence, but maybe the following may give you some ideas.

When I open "Select icons and notifications appear in the task bar" one of the things it lists is "GLBD565.tmp" which seems to be left by the installation of a software product. The icon is not active and I doubt if it still exists, but it appears in the list. That list is maintained and how to remove the dead of her spots?
The entries to Customize Notifications cannot be removed selectively. You can, however, clear the set lists by using the following registry change.
Click Start, type regedit in the Search box and press ENTER.
- Locate and then click the following registry subkey:Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify HKEY_CURRENT_USER
- In the Details pane, click the IconStreams registry entry.
- On the Edit menu, click delete, and then click Yes.
- In the Details pane, click the PastIconsStream registry entry.
- On the Edit menu, click delete, and then click Yes.
- Exit Registry Editor.
- Restart the Explorer.exe process. To do this, follow these steps:
- Press CTRL + SHIFT + ESC.
- On the process in the Task Manager tab, click the process explorer.exe and then double click on end process .
- On the file menu, click new task (run), type Explorer and click OK.
- Exit Task Manager.

I want to permanently delete an item from my library and computer - Windows, iTunes 12.3.3.17
I read this post from Apple. But I do not get option 3.
Can someone please help.
Link: 12 iTunes for Windows: delete the songs, playlists or other elements
Option not to get:
Do one of the following:
- Remove the item from your iTunes library only: click on a file to keep.
- Remove the item from your computer: click on move to the trash. The item is deleted the next time you empty the trash.
The exact behavior on deletion depends on the location of the file in question as iTunes encourage you only to recycle the files located in the iTunes Media folder. Behavior also differs if you are working in a playlist rather than saying the main music source. Shift + delete can be used to remove it from the library while you watch a playlist. Removal of media bought may lead to additional confirmation dialog boxes, as well as the use of iTunes game or Apple's music.
If you keep your media outside of the folder of media to iTunes standard see KillSelectedFiles for a script that does just what it says.

In October, my Windows Mail simply stop allowing me to remove anything. I noticed it first in my Inbox, so I went to my "deleted items" empty to make (thinking that it was question) instead, but found that I could not delete individual emails or use the tool to empty folder. Windows Mail doesn't allow me to delete ALL emails from ANY folder, so now I need to access my emails on the internet, but it's a pain that my address book is in position.
I googled solutions and tried a few corrections people recommended when they are unable to remove files from a single folder. They don't solve anything. I thought corrupted program so I would update and downloaded Windows Live Mail hoping to fix it, but same problem remains.
Error message when you try to delete individual reading by e-mail: "Message could not be deleted." Error message when you exit the program: "certain elements in the"Deleted items"folder cannot be deleted. An error has occurred. "Nothing specific, but ANY element of ANY folder can be deleted.
